kernel Oops with 2.6.35.2 and glxinfo (or other GL programs)

kernel Oops with 2.6.35.2 and glxinfo (or other GL programs)

[Andreas Sundstrom]

On my laptop X hangs as soon as something uses OpenGL.
Running for example glxinfo or glxgears causes it to freeze.
I have not had any issues like this before, and 2.6.34 works ok but not 2.6.35.2

I have pasted the Oops here: http://codepad.org/t1aVjAzy

I will include it with this email too, but to avoid problems with the formatting
I have provided the link above.

This is on a HP Compaq 6910p laptop running Debian Lenny

I used git bisect for the first time and it took a while but finally this commit was shown
by git as the offending commit:

8187a2b70e34c727a06617441f74f202b6fefaf9 is first bad commit

    drm/i915: introduce intel_ring_buffer structure (V2)

    Introduces a more complete intel_ring_buffer structure with callbacks
    for setup and management of a particular ringbuffer, and converts the
    render ring buffer consumers to use it.

I was not able to revert this commit from 2.6.35.2, but maybe it can be a pointer in the
right direction for someone that knows this stuff?

I'm not sure what else to provide? Let me know if I can do something to test
this further..

I'm not subscribed to the list so feel free to CC me on any replies.

Any help is appreciated
